Abstract (en)
[origin: EP2405234A1] A form measuring instrument (1) includes an instrument body (2) and a controller (3) that controls the instrument body (2). The instrument body (2) includes a probe (4). The probe (4) includes: a rod-like stylus (41) having a distal end attached with a stylus tip for contacting with an object; and a support mechanism (42) that supports the base end of the stylus (41). The support mechanism (42) includes a probe sensor (421) that detects the position of the stylus (41) and supports the stylus (41) in a manner movable within a predetermined range. The controller (3) calculates a measurement value based on a transfer function whose input is the position of the stylus (41) detected by the probe sensor (421) and output is the contact position of the stylus tip against the object.
